Problems We Encountered Too Much Programmed Motion Should have put in more time in the first week more sensors / better sensing techniques

Why Wont You Start! During the actual demo day our robot wouldn’t get past its initial delay. Had to start the program in a different location then normal. We suspect auto-start had something to do with it.

The Ghetto Look

Finite State Machine Couldn’t recover when things went wrong

One sensor on the front Robot scans by rotating when it looses the light its heading for. No shielding around phototransistor to detect light from any of the forward directions Sometimes would detect lights in different parts of the course while scanning.

Detecting the Intersecting Lines Outer pairs were used to detect the intersections on the table. Inner pairs used to follow the correct line.
